Built for paycheck questions
What PayRulesHub helps you estimate
PayRulesHub is a free calculator library for common work and payroll questions: how much overtime may be worth, how PTO accrues, what an hourly wage equals as a salary, how severance formulas work, and how gross pay can differ from take-home pay. The tools are designed for quick planning before you compare the estimate with a pay stub, offer letter, employer policy, or official agency guidance.
We focus on transparent math. Each calculator explains the basic formula, common assumptions, and the situations where a real payroll result may be different, such as deductions, local taxes, benefit elections, state wage rules, or employer-specific policies.

Review checklist
Before relying on a paycheck estimate
Check your pay period
Weekly, biweekly, semimonthly, and monthly schedules can produce different per-check amounts even when the annual pay is the same.
Confirm deductions
Health insurance, retirement contributions, garnishments, and other deductions can change net pay beyond the calculator's simplified assumptions.
Verify state rules
Overtime, final paycheck timing, and PTO payout rules vary. Use our state guides as a starting point, then confirm with official sources when money is at stake.
